But that Recessiveness is not a _minus_ sign merely, as algebraically understood--but is an essential potence on another, and a psychical plane, is shown by the lesser height of woman rendering itself as a Grace; her lesser strength appearing in the new virtue of Gentleness. That the female provides, for fertilisation, only a single sex-cell, from the reproductive gland of one or other side, while the male provides multiple and commingled cells from both sides, supports the view that sex-cells derived from one side are of opposite sex-inherence to those from the other side. Otherwise, why two reproductive glands? The author of _The Causation of Sex_ adduces evidence showing not only that the two glands are of opposite sex-inherence, but, moreover, that normally they function alternately; so that now a cell of one, now, of the other sex, is produced. It is likely, however, that function is seldom so mechanical, but that personal constitution or nurture modifies its operations. That the male cells are multiple in number points to such a struggle of survival-fitness as ever characterises the more strenuous male destiny. Not, perhaps, the fittest as regards intrinsic superiority, but that most compatible with the requirements of the Queen-cell is selected for mate. Should the Queen-cell be of inferior standard, therefore, then (as happens in life) not the noblest of type, but that most adapted to environment secures racial survival. So that here again, evolutionary racial advance may derive its impulse from the Female factor. A singular phenomenon, recorded by the biologist, Rörig, and one which materially supports my argument, is that disease of the ovaries of a female deer will cause _male_ antlers to develop in her. Proving a male organism concealed, or held Recessive, in her, by power of her female sex-organs normally to inhibit the development of her inherited male-traits. A strange feature of this abnormal occurrence is that disease of _one_ ovary only causes antlers to develop on _one_ side only--and this on the side opposite to that of the diseased gland. On the other hand, castration of male sheep of the Merino breed (only the males of which are horned) occasions hornlessness. V Male traits being paramount on the plane of concrete function, although they exist (normally) in Recessive form in the female, it is from the male inherence of her active right side and its allied brain-half that she derives her concrete powers alike of body and of brain. It is obvious, therefore, that when abnormally stimulated by undue exercise, such male-traits may develop into abnormal dominance.
